SPECIFICATION forming part of Letters Patent No. 658,474, datedSeptember 25, l1900.

Application filed January 2, 1900I Serial N o. l0. (No model.)

To all whom it Wwf/y concern: 4

Be it known that I, CHARLES F. SPARKS, a citizen of the United States,residing at Alton,

Madison county, Illinois, have invented a certain new and usefulCloth-Cutting Machine, of which the following is such a full, clear, andexact description as will enable any one skilled in the art to which itappertains to make and use the same, referencebeing had to theaccompanying drawings, forming part of this specification.

My invention relates to a machine for cutting strips of a predeterminedlength from a roll of cloth, and is especially adapted to cutting clothfor the manufacture of bags, such as are used in packing flour.

My invention consists in part in the combination, with a rotary memberaround which the material passes, of a cutter carried in said rotarymember and adapted to project beyond the same, and means for feedingsaid cutter longitudinally of said rotary member.

My invention also consists in various other j novel features and detailsof construction,

all of which are described in the following specification and pointedout in the claims afiixed hereto.

In the accompanying drawings, which illustrate one form of machine madein accordance with my invention, Figure 1 is a longitudinal sectionthrough a portion of the main or cutting cylinder. Fig. 2 is across-section of the same. Fig. 3 is an end View, on a reduced scale, ofthe complete machine. Fig. 4 is a side view. Fig. 5 isa diagrammaticalvertical section. gearing. Fig. 7 is a section showing a detail ofconstruction. Fig. Sis a side view of the part shown in Fig. 7. Fig. 9is a side View showing a detail of construction, and Fig. 10 is a viewshowing a modification.

Like marks of reference refer to similar parts in the several views ofthe drawings.

is the main or cutting cylinder, which is vjournaled in end frames 16and 17. Journaled in the frames 16 and 17 below the cylinder 15 is asecond cylinder 18.

19 is a cylinder, also journaled in the end frames 16 and 17 andsituated at the rear of land slightly below the cylinder 18.

2O is the roll of material from which the Fig. 6 is an end View showingthe;

strips are to be cut. Said roll 2O is journaled in frames21. n

22 represents guide-rollers which are journaled in the end frames 16 and17, and 23 is a driving-shaft also journaledin said end frames andprovided with a driving-pulley 24. The driving-shaft 23 has secured toitaspur-wheel 25, which meshes with a spur-wheel 26, secured to one of thetrunnions 27 of the main or cutting cylinder 15. AThe spur-wheel 26meshes with a spur-wheel 28, secured to the shaft 29 of the cylinder1.8, and the spurwheel 28 meshes with a spur-wheel 30,secured to theshaft 31 of the cylinder 19.

Secured within the main or cutting cylinder 15 is a guide 35, which isarranged adjacent to the part of the cylinder in which is formed alongitudinal slot 36. Secured to the guide 35 are crossbars 37, fromwhich is supported a rack-plate 38. At each end of the rack-plate 38 isa sprocket-wheel 39, journaled on a shaft 40, carried in the rackplate38 and cross-bars 37. Around the sprocket-wheels 39 passes an endlesssprocketchain 41. Secured to one of the sprocket wheels 39 is a bevelgear-wheel 42, which meshes with a bevel gear-wheelV 43, carried on ashaft 44, passing through the cylinder 15. Secured to the end of theshaft 44 is a spur-wheel 45, which meshes with a stationary spur-wheel46, secured to the end frame 17. Secured to the sprocket-chain 4l aretwo wings, which embrace the guide 35. The wings 47 have journaled inthem a stud 48, to which is secured a rotary cutter 49 and a spur-wheel50. The end of the stud 48 preferably runs in a guide 5l to steady thecutter 49. The spur-wheel 50 meshes with the teeth on the rack-plate 38.The rotary cutter 49 projects through the longitudinal slot 36 andbeyond the cylinder 15, as best shown in Figs. 1 and 2.

52 is a block of emery or other suitable grinding material, 'againstwhich the rotary cutter 49 is adapted to bear in its return movementwithin the cylinder 15, so as to sharpen the said rotary cutter 49.

The cloth is prevented from slipping b y licher-in points 53, which areprefera'blyrar- -ranged in two rows on the periphery of the cylinder 15.

IOO

The cylinder 15 instead of being circular in cross-section may be madeoval, as shown in Fig. l0, to change the'girth of the cylinder, andconsequently the length of cut,with out otherwise altering the machine.When this is done, the cylinder 18 must be shaped correspondingly, sothat its periphery will travel at the same speed.

Journaled in the cylinder 18 is a shaft 55, carrying fingers 56, whichare adapted to grasp the end of the material on the cuttingcylinder 15.The shaft 55 is actuated by means of a cam 57 coming in contact withpins 58 and 59, carried by the end frame 16. Carried in the cylinder 18is a folder-blade 60, which is actuated by means of a pin 61, carried ona shaft 62, journaled in said cylinder 18. The sli-aft 62 is actuated bymeans of a cam 63 striking a pin 64, carried by the end frame 17.Journaled in the cylinder 19 is a shaft 65, provided with fingers 66,adapted to grasp the cloth from the folder-blade 6() of the cylinder 18.The shaft is actuated by means of a cam 67 striking pins 68 and 69,carried by the end frame 16. Below the cylinder 18 is a shaft 70, overwhich the end of the material is drawn by the cylinder 19. Below thecylinders 18 and 19 is a table 71.

One of the wings 47 may have secured to it an arm 75, carrying aguard-plate 76 for preventing the material from being raised olf of thecylinder by the rotary cutter 49. One side of this guard-plate 76 ispreferably formed into a cutting edge 77, Fig. 7, to cooperate With therotary cutter 49 and make a shearing cut. In place of the guard-plate 46a small rotary cutter 78 may be carried on an arm 79, secured to one ofthe Wings 47 and driven by contact with the rotary cutter 49.

The operation of my machine is as follows: The material passes from theroll 20 over the guide-rollers 22 to the main or cutting cylinder 15. Asthe cylinder 15 is rotated the pinion-Wheel 45 is driven by contact witha spur- Wheel 46 and rotates the shaft 44. This communicates motion tothe sprocket-wheel 39 by means of the bevel gear-Wheels 42 and 43, thusdriving the sprocket-chain 41. As the rotary cutter 49 is movedlongitudinally by means of the chain 41 the said cutter is also rotatedby the engagement of the spur- Wheel 50 with the tooth-rack 38, and thussevers the material around the cylinder 15. The end of the severed stripof material is grasped by the fingers 56 on the cylinder 18 and carriedaround until the central portion of the strip is adjacent to thecylinder 19, when said portion is forced outwardly by means of thefolder-blade 60 and grasped by the iingers 66 of the cylinder 19, theloose end being drawn over the roller70. As soon as the strip ofmaterial has beenfolded it is released by the fingers 66 and falls uponthe table 71.

Having fully described my invention, what I claim as new, and desire tosecure by Letters 1.
